title: fibonacci
tags: math,list,intermediate
Generates a list, containing the Fibonacci sequence, up until the nth term.
Starting with 0
and 1
, use list.append()
to add the sum of the last two numbers of the list to the end of the list, until the length of the list reaches n
.
If n
is less or equal to 0
, return a list containing 0
.
代码实现
def fibonacci(n):
if n <= 0:
return [0]
sequence = [0, 1]
while len(sequence) <= n:
next_value = sequence[len(sequence) - 1] + sequence[len(sequence) - 2]
sequence.append(next_value)
return sequence
使用样例
fibonacci(7) # [0, 1, 1, 2, 3, 5, 8, 13]
